Specification of Letters Patent.

Patented Aug. '29, 19106..

Application filed November 20, 1915. Serial No, 62,541.

To all whom it may concern:

Be it known that I, HENRY HANooLL, a subject of the King of England,residing in London, England, have invented certain new and usefulImprovements in Hose-Couplings, of which the following is aspecification.

This invention is for improvements: in or relating to a hose-union andto a method of constructing it. 'As each half-coupling of a hose-unionis identical a description of one of them Will suffice for both.

According to the present invention a method of constructing ahalf-coupling for a hose-union in which two metal members are to beengaged with freedom for relative rotation is characterized by thedeformation of a flange or projection on one of them into a pocket inthe other by a face constituted by one wall of the pocket or by asurface provided for the purpose and adjacent to that pocket. Moreparticularly in forming such a half-coupling the two metal members areprovided with bearing-surfaces which abut at the finish of the operationof deforming the flange or projection so that the bearing-surfacesconstitute a stop limiting the degree of relative movement which can beimparted tothe members during the operation of the deformation of theflange.

The invention also includes a half-coupling constructed by the methodsabove referred to.

Other features of the invention Will be more clearly understood byreference to the following description taken in connection with theaccompanying drawings which illustrate one preferred embodiment of theinvention and in which Figure 1 is a central section of the two membersof the device when they are assembled and interengaged, and Fig. '2 ismainly a central section of the two members separated from one anotherbefore being assembled and interengaged.

The drawings illustrate,'in detail, a halfcoupling of a hose-union ofwhich, as will be seen in Fig. 2, the inner member A constitutes, at theend A a sleeve to which the hose may be attached in any desired man nerwhile at the other end it is provided with an enlargement, designated asa whole by the reference character A The part A is formed with aprojecting annular flange B which extends mainly in an axial directionand which may be conveniently formed by removing or cutting away thematerial at the region of the face B The enlargement A is also providedwith an undercut portion, as at C, to receive the flange of a packingring as will be hereinafter described.

.The outer member D of the coupling is formed so that its internaldiameter, at the surface D is sufficiently large to enable it to passover the projection B while at the surface D the diameter is sufficientto allow the member to slide over the end A of the member A. An annularslot or pocket is formed at D and the mouth of the pocket 1s 'sodisposed that as the outer member is caused to slide along over theinner member the projection B will pass into the pocket.

In assembling the two parts after the flange B has passed into thepocket D it will be engaged by one wall, such as D, of the pocket andwill be deformed until it assumes the position and formation illustratedin Fig. 1 and the limit of its deformation is determined by thebearing-surface D abutting against the surface B It will be seen fromconsideration of Fig. 1 that after the flange 13 has been deformed 1nthe manner described, it becomes locked within the pocket to prevent thewithdrawal of the two parts from one another although the dimensions ofthe pocket and the flange may be such as to allow a certain limited playbetween the two parts. The construction is such, however, that themembers A and B may rotate independently of one another.

The recess C in the enlargement A receives the flange of a compressiblering, for example a rubber ring, E, which may be easily deformed andsprung into place as will be readily understood.

The outer member-is provided with the usual hooked extensions as at F atopposite ends of a diameter, also with cam or wedge surfaces G and gapsG between the commencement of the wedge surface and the hook so that asimilar cooperating halfcoupling may be engaged with it in the customarymanner. Such an engagement will cause a compression between the packingring E and a similar packing ring on the cooperating half-coupling tobring about the required fluid-tightness of the joint.

It will be at once seen that the advantages of the present invention arethat the customary locking and packing rings used in connection with theouter member to hold it in position on the inner member are done awaywith, while the efiiciency of the cou pling and the ease with which itmay be manipulated are in no way impaired;

Although one particular construction of hose-coupler according to thisinvention has been described in detail with the aid of the 1accompanying drawings, it is obvious that modifications may be made inthe details as may be found convenient provided always that the spiritof the invention, as defined by the claims, is not departed from.

What I claim as my invention and desire to secure by Letters Patent is1, A hose coupling member comprisng an innertube provided with acylindrical boss,

and hook on the opposite member, substantially as described.

2. A hose coupling member comprising an. inner tube provided with acylindrical. boss, said boss being provided at its front end with anannular chamber having an over-hanging lip at its orifice and at itsrear end with a rearwardly projecting annular rib, an outer ringrevolubly mounted on said inner tube, and having a cylindrical chamberadapted to receive said cylindrical boss, and an annular grooveprojecting at an angle rearwardly and outwardly said annular ribengaging and being distorted by said annular groove, thus locking saidtube and said ring in engagement, said ring he ing provided with a hookand cam surface adapted to engage a corresponding cam surface and hookon the opposite member, and a packing ring sprung into said annularchamber and locked in place by said over- 7 hanging 1ip,,substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
